A helicopter moves with a constant velocity v, - 4 m/s from point A to point B during a time
interval tas = 10 s. It then accelerates from point B to point C with constant acceleration az =
2m/s2 for a time interval tac = 20 s. The average velocity of this helicopter for the whole trip is
equal to:
A
tas-10
tec-20 s
Q2 = 2m/s2
Di=4 m/s

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
